warc = Web ARChive File Format.
Warc files with extension .warc or compressed warc.gz can be placed in the
DATA/surrogate/in and contained responses are imported to the index.
The used library is stream based so we can easily extend it later to use
and load warc's from the net.
- enabled HTTP POST calls with Digest HTTP authentication
- made API calls compatible with API newly restricted to HTTP POST only
with transaction token validation
- ensured backward compatibility with older entries recorded as HTTP
GET
- ensure use of HTTP POST method : HTTP GET should only be used for
information retrieval and not to perform server side effect operations
(see HTTP standard https://tools.ietf.org/html/rfc7231#section-4.2.1)
- a transaction token is now required for these administrative form
submissions to ensure the request can not be included in an external
site and performed silently/by mistake by the user browser
When programmatically requesting the local peer with Apache http client,
authentication credentials must be passed as clear-text values.
This extension to the apache org.apache.http.impl.auth.DigestScheme
permits use of the YaCy encoded password stored in the
adminAccountBase64MD5 configuration property.
Because curl and wget do not let use a hashed password as parameter,
YaCy shell scripts which require authentication are now interactive by
default when HTTP Digest is the only available authentication method.
Batch mode can still be available trough the use of an environment
variable : YACY_ADMIN_PASSWORD.
Other improvements :
- added backward compatibility for Basic Authentication
- fixed curl/wget presence detection
- do not return with exit code 0 when an API call failed, and print an
error message when the case occurs
- documented available authentication options for API calls
A port value of -1 will disable this option.
If set to a value greater 0, YaCy listens on this of on the local loopback
address (127.0.0.1) for a shutdown or restart signal.
E.g. connect to http://localhost:8005/shutdown will stop the YaCy server.
http://localhost:8005/restart will restart it.
This option allows to stop YaCy locally independant from the web web
frontend (which might be configured for password protected remote access).
This is a fix for mantis 715 (http://mantis.tokeek.de/view.php?id=715).
A possible path scenario that could leading to this case :
- YaCy is running low in memory
- a search is requested
- before the end of search results rendering, the cleanup job runs and
deletes the running search event from the cache because of short memory
- then yacysearchitem renders with "-UNRESOLVED_PATTERN-" parameter
values passed to the statistics() JavaScript function
by using icu.ULocale for languages not already covered (ICU normalizes
to ISO639-1 2 char codes).
Add test class
Use DublinCore vocabulary declarations in DCEntry and SurrogateReader
for easier usage debugging,
Init SurrogateReader.inputSource on first use.
following comment "use of properties as header values is discouraged"
in case where (proxy)HTTPClient overwrites values with supplied url.
Use defined request.referer procedure in response class.
HTTP "Referer" header sent by the browser when using YaCy can now be
controlled either with the referrer meta tag as a global policy, or only
for search result links by adding the attribute rel="noreferrer".
To improve privacy with the less possible regressions, the default is
set as meta tag with value "origin-when-cross-origin" : internal YaCy
links behavior is not affected, but when visiting external websites
referrer url is not empty but stripped from query parameters and path.
Older browsers, Safari, MS IE and Edge do not support the referrer meta
tag, so the standard but less flexible noreferrer link type can also be
enabled as an alternative.
User-friendly settings page to be implemented.
low number of found documents - by adding additional end condition to
remove processed query with number of found docs <= process-chunck-size.
Noticed on query h4_txt:[* TO *], found 21, process 21, call of commit happend
but on next cycle same query again 21 docs found (while h4_txt was removed
from schema and committed inputdocuments).
The datacite Solr search http URL was returning http status 301 in order
to redirect to its https version, thus making that YaCy heuristic always
fail.
